The MARQUESS of LONDONDERRYI feel myself bound to state to the House, with regard to the letter I presented and commented upon on a former day [vol. cviii. p. 1276], purporting to be signed by the Rev. Mr. Rutherford, that letter turns out to be a forgery. I have received two notes with respect to the transactions in question, which I wish to lay on the table of the House. One of these is from the Rev. Mr. Dobbin, who wrote the first letter which I received, and which that gentleman does not now deny. But he states that he had no connexion with the letter purporting to come from Mr. Rutherford directly or indirectly; and that he has just seen Mr. Rutherford, who authorises him to say that the letter is an entire forgery. I have likewise a letter from Mr. Rutherford himself, denying the authenticity of the document purporting to bear his signature, and stating that he has not the slightest knowledge of the person by whom the letter was written. Now, my Lords, without reading these notes at length, I may leave them upon the table of the House for your Lordships to refer to; and I have only to add, that if I have been egregiously imposed upon, I submit whether it was not very natural that I should consider Mr. Rutherford's letter as genuine, when I read to your Lordships the words of that rev. gentleman, as reported in almost all the papers in the north of Ireland. [His Lordship then read some extracts from Mr. Rutherford's speech.] I have only further to state, that having received a letter from the Marquess of Downshire's agent, informing me that he did not get up the meeting to address his Lordship at Hillsborough, and that the matter was first mentioned to him by a respectable tenant—thence its origin—I can only say that I quoted from the press of the day, and I can now assure your Lordships that I very much regret stating anything disrespectful to the large body of independent tenants of the noble Marquess. I may take the opportunity of stating, before I sit down, that I have been induced by the matters in question, to address a letter to his Excellency the Lord Lieutenant, and that I have received an official answer from his Lordship, with every word of which I entirely concur. I only regret that his Lordship's secretary has thought fit to publish the answer without annexing to it the letter which called it forth.
